Trimmer Potentiometers

A trimmer potentiometer, also known as a trimpot or trimmer, is a variable resistor that is mainly used to control the exact amount of resistance in various circuits. Trimmer potentiometers typically have an adjustable arm or lever, and a small rotating knob for adjusting the resistance. The adjustment arm is usually connected to the central wiper of the potentiometer, which is also connected to the resistance terminals. Changing the position of the arm or rotating the knob adjusts the amount of resistance by changing the amount of contact the wiper has with the resistive track.

The 3250P-1-103 is a ceramic trimmer potentiometer with a 1kOhm resistance and 10% tolerance. It comes in a variety of packages and with six printed circuit board mounting options. The 3250P-1-103 has three terminals: a terminal for the wiper, one for the start of the resistive track, and one for the end of the resistive track. The length of the resistive track is approximately 3.2mm, the tolerance of the resistance is +/-10%, and it has an operating temperature range of -55 to +125°C.

The 3250P-1-103 trimmer potentiometer is mainly used in applications such as volume control for audio amplifiers, cutoffs for pre-amplifiers, and various other applications for adjusting resistance. The 3250P-1-103 is made of a non-magnetic ceramic body and is lead-free with a RoHS certification. It is durable enough for harsh environmental conditions such as high humidity, heat, and vibration.

The 3250P-1-103 trimmer potentiometer is easy to use and adjust. It features a double-bearing locking mechanism for fixing the wiper and a locking screw that allows the user to adjust the wiper without moving the other parts. To adjust the resistance, the user simply needs to loosen the locking screw and move the wiper to the desired position. Then, the locking screw can be tightened to fix the wiper in place. The 3250P-1-103 is ideal for applications where precise resistance adjustment is needed and it is a reliable and cost-effective solution.
